Common emitter transistor amplifier

AI Thread Summary
In a common emitter transistor amplifier discussion, key parameters include Rc at 5k ohm, R1 at 100k ohm, R2 at 27k ohm, Re at 3.3k ohm, beta at 200, and Vs at 12.7V. The transistor reaches saturation with Vce at 0.3V, and the DC voltage between the collector and ground is measured at 7.7V without a signal. Participants express confusion regarding the calculation of base, emitter, and collector currents, especially since the standard Ib=Ic/beta formula may not apply in saturation. A request for a schematic diagram indicates a need for visual aid in understanding the circuit. Overall, the discussion focuses on calculating transistor parameters in a saturation context.

Rc= 5k ohm
R1=100k ohm
R2= 27k ohm
Re=3.3k ohm
beta=200
Vs=12.7V

Vce= 0.3V at saturation

With no signal applied, dc voltage btw collector ans ground measured as 7.7V

Calculate the transistors base,emitter,collector currents

Ive only come across problems with transistor in linear region so I am confused where to start as I learned that Ib=Ic/beta no longer valid.

Please help.
